I have a 2014 with perf pkg, recently added Borla exhaust, Steeda CAI, BBK t-body and a tune. All my driving is in town (stop and go), with the changes I've jumped from 16.9 to 18.4. But, then I now use 91 octane, so probably still costing me more.

2014, V6, manual, Gray, Perf Pkg, Prem Pkg, Borla exhaust, BBK TB, Steeda CAI, Bama Tune.
